This is a small article about understanding the liveness, readiness and startup in kubernetes. There's good explanation in the kubernetes documentation: https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/ This video also explains well the process: https://www.youtube.com/watch?v=aTlQBofihJQ But I wanted to understand it in a practical way. So I have this demo: https://github.com/DiegoTc/guest-book-js-docker/tree/Running-App-Version-1 It's a simple application running on a kubernetes cluster. https://github.com/DiegoTc/guest-book-js-docker/blob/Running-App-Version-1/argo/deployment.yaml apiVersion: apps/v1 kind: Deployment metadata: name: chat-ui spec: replicas: 1 revisionHistoryLimit: 3 selector: matchLabels: app: chat-ui template: metadata: labels: app: chat-ui spec: containers: - image: diegotc/guestbook:20230803-064434 imagePullPolicy: Always nam
One of my favorite applications for taking screen shots in Ubuntu is Screecloud unfortunately there's no version available for Ubuntu 16.04.

Steps for installing Screencloud at your own "risk" Ubuntu 16.04
- Download libqtmultimediakit1
- wget http://de.archive.ubuntu.com/ubuntu/pool/universe/q/qtmobility/libqtmultimediakit1_1.2.0-1ubuntu2_amd64.deb
- sudo dpkg -i libqtmultimediakit1_1.2.0-1ubuntu2_amd64.deb
- sudo apt-get install -f
- We need to modify our source list
- sudo nano /etc/apt/sources.list
- We add the following line to the end of the file
- deb http://cz.archive.ubuntu.com/ubuntu wily main universe
- We install screencloud
- sudo sh -c "echo 'deb http://download.opensuse.org/repositories/home:/olav-st/xUbuntu_15.10/ /' >> /etc/apt/sources.list.d/screencloud.list"
- sudo apt-get update
- sudo apt-get install screencloud
- We just open a console and type screencloud and the application will begin running.
- We remove from the source list the deb file we added in step 2
- sudo nano /etc/apt/sources.list
